------- Comment #2 from phelps at gnusto dot com 2007-12-11 10:38 ------- Created an attachment (id=14728) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14728&action=view) proposed fix
I'm seeing similar behavior on x86-64 with both g++-4.1.3 (ubuntu-7.10 dist) and g++-4.2.2 build from sources. I spent some time in the debugger and I've identified the problem and a fix. It looks like the problem first appeared in r115654. The change to eh_personality.cc guards a call to _Unwind_GetIPInfo with the preprocessor macro HAVE_GETIPINFO. Unfortunately, that macro HAVE_GETIPINFO is never defined in c++config.h; _GLIBCXX_HAVE_GETIPINFO is. The attached patch (against gcc-4.2.2) fixes this issue and the resulting libstdc++.so.6.0.9 produces the desired behavior. Thanks, -Ted -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34152
